Urinate over electric fencing implement (4)

Ross

I believe the answer is:

epee

I'm a little stuck... Click here to teach me more about this clue!

'fencing implement' is the definition.
(I've seen this in another clue)

'urinate over electric' is the wordplay.
I cannot really see how this works, but
'urinate' could be 'pee' (synonyms) and 'pee' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for epee that I've seen before include "Fencing sword similar to a foil" , "Fencing weapon" , "Duelling weapon" , "piece of fencing" , "Narrow fencing sword" .)

I've seen this clue in the Sydney Morning Herald.
